Precautions
Installation place
• Install this unit in a horizontal and stable place where the
unit is less subject to external vibration.
• Do not install this unit near a television or color monitor.
Keep this unit away from such devices as cassette decks
that are subject to magnetism.
Do not move this unit during playback.
Moving this unit during playback may cause the needle jump,
and damage the needle and the record thereby.
When moving this unit
To move this unit, be sure to turn off the power after stopping
the turntable and removing the record. Next, unplug the pow-
er and phono cables, remove the turntable and the turntable
sheet, and move this unit.
Avoid the following locations for installation.
• Locations exposed to direct sunlight
• Places subject to humidity and with less ventilation
• Places where are extremely hot or cold
• Places subject to vibration
• Places subject to dust
• Places subject to oil, steam, and heat (such as kitchens)
Lubrication
Do not lubricate this unit yourself because special oil is used
for the spindle.
Cleaning
• Usually, wipe the unit with a dry soft cloth.
When the dirt is hard to remove, dip soft cloth in detergent
diluted 5 or 6 times with water, wring it well, and remove
contaminants. Then, remove the moisture with dry cloth.
• Be aware that acrylic portions such as dust cover may be
damaged if the portions are rubbed hard.
• Be aware that printed or painted portions may be damaged
if the portions come into contact with alcohol, thinner, ben-
zine, insecticide, or the like. In addition, do not let this unit
contact a rubber or plastic form for a long time. That may
damage the cabinet surface of the unit.
• When using a chemical cloth for cleaning, read the caution
provided with the chemical cloth product.
• Be sure to unplug the power cable from the outlet before
cleaning.
Repair and adjustment
When repairs and adjustments are needed, please ask the
dealer where you bought the unit.
Do not put articles.
Do not put any articles on this unit.
To avoid heat emission
Do not place this unit on such device as an amplifier that may
emit heat. If the unit is installed on a rack, install the unit as
distantly as possible from where the amplifier is installed so
as to avoid heat emission from the amplifier and other audio
devices.
Dew condensation
Be aware that condensation may occur when this unit is
moved from a cold place to a warm place especially in win-
ter or when the temperature of the room where this unit is
installed is quickly raised with a heater or the like. It depends
on the condensation state, however, this unit can be used
after water droplets disappear by turning on the power and
leaving the unit as it is for 1 to 2 hours to keep the unit at room
temperature.
Even in summer, dew condensation can occur if this unit is
directly exposed to cool air from an air conditioner. In such
a case, it is recommended to change the installation place.

Features of This Unit
Belt drive
A new drive system is introduced, in which motor-derived
noise is attenuated via a belt and smooth rotation is achieved.
Circuit configuration
AC synchronous motor is driven by sine waves coming from
32-bit microprocessor, which are DA converted and amplified
by a high-power audio amplifier.
Stroboscope
This unit is equipped with a reflective view type LED strobo-
scope to adjust the rotation speed precisely.
Arm base
This unit is finished with chromeplated and spin-stabilized
brass with 20 mm in thickness.
By replacing with the optional arm base, various types of tone
arms can be mounted, which allows users to enjoy sound
changes.
Tone arm
A universal static balance tone arm is included as a standard
equipment for the simple cartridge replacement.
Heavyweight platter
The platter weighs 5.0 kg, which is machined from aluminum
metal to improve rotational accuracy.
Approximately 0.7 t·cm2 of moment of inertia has been
achieved.
High rigidity main chassis
This unit uses an underslung vibration-damping structure ca-
pable of hanging internal main parts using machined alumi-
num plate with 15 mm in thickness as a base.
Large-sized spindle
This large-diameter spindle is equipped with polyether ether
ketone (PEEK) bearing of ball bearing specification that pro-
vides stable rotation.
2
Floating mount
The power transformer and the motor are “floating-mounted”
with rubber cushions to isolate vibration to the main chassis.
Hybrid vibration damping
The bottom face of the cabinet has a hybrid vibration-damp-
ing structure made of wood and metal for resonance disper-
sion.
Large-sized insulator
This unit adopts a damper as an insulator that is a combina-
tion of rubber and spring, made from different materials to
isolate unnecessary vibration coming from an audio rack or
others.
Unnecessary vibration from the main chassis itself is also
suppressed.
Magnesium alloy headshell
Magnesium alloy headshell with LUXMAN logo is supplied.
LED stylus light
The detachable high-intensity LED stylus light is supplied for
operation in the dark.
AC inlet
Power-cable-detachable AC inlet.

1. Power switch (OPERATION)
This switch turns on and off the power.
2. Operation indicator
This indicator lights up when the power is turned on.
3. Start/stop switch (start/stop)
This switch starts rotating the platter at the selected rotation
speed.
This switch also stops platter rotation while the platter is
rotating because this switch serves as both start and stop
switches.
6
4. Rotation speed selection switch (33/45)
This switch toggles the rotation speed of the platter be-
tween 33 rpm and 45 rpm.
Select a rotation speed in accordance with a record to listen
to.
5. Strobo Scope
This window shows the number 33 or 45 depending on the
number selected by the rotation speed selection switch. If
the number is motionless, the rotation speed is fine-tuned.
9. Center spindle
This spindle is a guide for mounting a record.
For playing an EP record, mount the EP adaptor here.
10. Belt
This belt transfers motor rotation to the platter.
11. Rubber mat
This rubber mat suppresses platter squeaks and brings a
record into intimate contact with the platter.
6. Rotation speed fine control (33/45 speed control)
33 rpm Fine-tunes the rotation speed. Please look into the
stroboscope and fine-tune until the number 33
completely stops moving, when the rotation speed
switch is set to 33.
45 rpm Fine-tunes the rotation speed. Please look into the
stroboscope and fine-tune until the number 45
completely stops moving, when the rotation speed
switch is set to 45.
7. Stylus light connector (light)
This light can illuminate stylus area in a dark room.
Remove the dustproof cap and mount the supplied stylus
light.
8. Pulley cover
This cover protects the rotating pulley.
Be sure to mount the cover when the platter is rotated.
12. Headshell
Headshell couples a cartridge with the tone arm.
13. Arm lifter
This lifter is used to move the tone arm vertically.
14. Anti-skating adjustment knob
This device cancels the inward force applied to the tone arm
during record playback.
Select a number in accordance with the cartridge to be
used.
15. Counterweight
This weight is used for adjusting tone arm balance and sty-
lus pressure.
